Mat\u00e9riaux<\/p>\n<p>Les mat\u00e9riaux doivent \u00eatre la priorit\u00e9. Il existe actuellement sur le march\u00e9 de nombreux types d&#039;aimants, tels que les aimants en n\u00e9odyme fer bore, samarium cobalt, aluminium nickel cobalt, ferrite et caoutchouc, etc. Le NdFeB poss\u00e8de le champ magn\u00e9tique le plus puissant. Cependant, il convient de noter que, m\u00eame pour un m\u00eame mat\u00e9riau, comme l&#039;aimant NdFeB, les nuances N35 et N52 sont tr\u00e8s diff\u00e9rentes.<\/p>\n<p>&nbsp;<\/p>\n<p>2.

Diff\u00e9rentes formes produisent des champs magn\u00e9tiques d&#039;intensit\u00e9 variable.<\/p>\n<p><img decoding=\"async\" class=\"lazyload\" data-src=\"https:\/\/www.cndailymag.com\/media\/144\/efabe784f6b16ee71d402329fe359b2.png\" src=\"data:image\/gif;base64,R0lGODlhAQABAIAAAAAAAP\/\/\/yH5BAEAAAAALAAAAAABAAEAAAIBRAA7\" \/><noscript><img decoding=\"async\" src=\"https:\/\/www.cndailymag.com\/media\/144\/efabe784f6b16ee71d402329fe359b2.png\"><\/noscript><\/p>\n<p>&nbsp;<\/p>\n<p>4.
